This is it.

The front and back flanges become the planet carrier further reducing
the cost and weight. A custom aluminum planet cage would
cost a lot in therms of NC machining time.

The Allison comes with 3 planet gears but you can put in
up to six. If you only use three the other three can be larger in
diameter spacers up to one inch which will stiffen it up. I think three
are enough as this is a real heavy duty transmission. Those planet
gears are rather heavy.

The bolts are ordinary  grade 8.... 7/16th bolts. The hollow planet shafts
 are about 5/8th OD and must be hardened and ground for the needle
bearings in the planet gears.

The correct size  shoulder bolts are hard to find. Also very expensive.

 I put in the helical gear thrust bearing. It is the blue bearing in the 3D's.

The planet shafts are recessed into the front and back flanges for accuracy
and torsional stiffness.
